What is nengchu-1 & how does it work?

The Nengchu-1 facility is located in Yingcheng and utilises two underground caverns of an abandoned salt mine, reaching up to 600 metres of depth, which serve as gas storage units. The technology allows a storage capacity of 1,500 MWh, which will ensure the stability of the grid and facilitate the integration of new renewable energy capacity.

How long can nengchu-1 store electricity?

The construction of Nengchu-1 was initiated in 2022. CEEC claims that the facility can store electricity for eight hours and release power over a five-hour period on a daily basis.

Why should China build nengchu-1?

“The successful grid connection of Nengchu-1 provides a Chinese solution to the global challenge of instability and uncertainty in new power systems dominated by renewable energy, contributing to the green and low-carbon energy transition,” said Song Hailiang, chairman of CEEC. The construction of Nengchu-1 was initiated in 2022.

What is the largest gas storage facility in the world?

According to the company, which also installed the capacity, this is the largest operating site of the kind in the world. The Nengchu-1 facility is located in Yingcheng and utilises two underground caverns of an abandoned salt mine, reaching up to 600 metres of depth, which serve as gas storage units.
